Frictional Force

.....AND OUR DAILY LIVES.

WHAT IS FRICTION?

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force-sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

ADVANTAGES OF FRICTION.

1.It becomes difficult to walk on a slippery road due to low friction.when we move on ice it becomes difficult to walk due to low friction of ice.

2.we cannot fix nail in the wood or wall without friction as it is friction which holds the nail
